Citrix screwed up recently with VDI-in-a-Box, creating a worldwide outage for every user of the product on January 1st. The proximate cause was a simple one, the Virtual Desktop Agent used by VDI-in-a-Box had a .dll which expired at midnight December 31st 2011 and the software wasn’t patched to address this. Like I said – embarrassing.
Now although it was a VDI product that had this problem wasn’t a VDI problem, it could have hit almost any product. I’ve seen this same type of failure take out many tens of thousands of PCs in one go and I’m sure it will happen again; people make mistakes.
